IMPROVEMENT IN BRICKMACHINES..

Specification forming part of Letters Patent No. 195,37 S, datedSeptember i8, 1877; application led March 20, 1877.

To all whom it may concern:

Be it known that I, HOSEA LINDSEY, of Asheville, in the county ot'Buncombe and State of North Carolina, have invented a new and usefulImprovement in Brick-Machines, which improvement is fully set forth inthe following specification, reference being had to the accompanyingdrawings.

The object of my invention is to construct a simple, substantial, andeasily-operated machine for the manufacture of bricks from wet clay.

Referring to the drawings, Figure 1 is a vertical sectional view ofthemachine. Fig. 2 is a top view, showing the empty molds resting upon thetable and ready to be moved under the hopper to be lilled.

A, Fig. 1, is the beam, to which the horse or horses are secured foroperating the machine. 'lhe ends of this beam are extended a sufficientdistance on each side for the purpose. F is the hopper for receiving theclay, which is made ot' the proper consistency and placed therein. B isthe shaft, which is provided with a suitable number of cutters orgrinders for tempering the clay, and at the same time feeding it to themolds. Ilhese cutters consist of sleeves E, which are secured to theshaft, and are provided with blades or wings C, similar topropeller-blades. Vertical pins D are secured in the under side of theseblades to facilitate the work. The lower of these cutters is constructedsomewhat different from the others. Instead of the blades being made ofa spiral or helical form, they are in a horizontal plane or at rightangles to the shaft, and the pins D are also omitted, so that the claymay be forced through orifices in the bottom of the hopper, and out offfrom the molds when they are moved under the shaft.

The hopper and its frame are mounted on a suitable table, G, having areciprocating bed, K. Two toothed cylinders, O O, are mounted inbearings in the frame that supports the hopper. These cylinders assistin the work otinixing and tempering the clay, and also of forcing itdownward in the direction of the molds, which rest on the reciprocatingbed.

The crank L is secured to a shaft in the frame of the table, and,turning the same, the molds are brought directly below the hopper, and,when filled, are moved outwardly at the other side of the table by meansof the crank.

Any other mechanism may be used for moving the reciprocatingbed-plate,as this peculiar feature I do not claim as novel. It is alsoobvious that the bedplate, may be rec-iprocated by power as well as byhand.

To operate the machine, the clay is placed in the hopper; the shaftcarrying the cutters or grinders is made to revolve; the reciprocatingbed bearing the molds is moved forward until the molds come directlybeneath the ori` tlces in the hopper, and, when filled, are movedforward until they extend beyond the hopper, when the full molds areremoved and empty ones placed in the front part ot' the bed, and theoperation repeated.

I claim as my invention- In a brick-machine, the combination of thereciprocating mold-table, the screw-feed, and pulverizing-rollers,arranged upon a suitable frame, substantially as and for the purposespecified.
